Well all right then. After some adventure involving throwing a tantrum because apparently static electricity caused my computer to reboot when I plugged a flash memory into it, I finally got everything together to make this post.

Alsamixer -c 1 showed that the HDMI was muted even though IEC958 was on in the default Alsamixer window. (See first image.)

After I unmuted IEC958 in the HDMI alsamixer window, I again first tried playing 2barks through the regular speakers to make sure it would work. Then I switched from device 0,0 to 1,3, and again got no sound even though there were no error messages. (See second image. Ignore the first line, the one with the red line through it. "bash: setenv: command not found" is there when I open rxvt. I don't know why.)

You have made progress.
- it's a good sign that alsamixer can access the HDMI port as card 1.
- it's a good sign that aplay plays the audio file without error.

Since DigitalTV and DVD both have a standard sample rate of 48 kHz, it might just be that your HDMI monitor might not be able to handle the 8 kHz sample rate of 2barks.wav.
I suggest you try to play a 48kHz uncompressed wav file. I just sent you a PM with a link to 48kHz and 44.1kHz test audio files.

Thanks, tempestuous. Both of the links were to the same 48 kHz file. It didn't play in HDMI but did in the Alsaplayer default audio..

I have a CD full of various wav files. They all seem to be 22.05 kHz mono, but since that's just half of a 44.1 kHz stereo I think it would play if a 44.1 kHz stereo file would. None of them would play in HDMI either.

After a reboot. When I open AlsaMixer. It ATI HDMI that is in the mixer... no chanel. I'm not able to get any sound.

So I open Alsa Wizard. Then select the first one Intel 18x0 and then its work. (note that noting refer to the ATI HDMI in Alsa Wizard.

After that I can open AlsaMixer and see my integrated audio card with all my channel and everything sound great.

But after a reboot, the problem is back.

Any clue to how make the sound come permanently from my main speaker ?
Also, I dont get the volume control near the clock... I have IceWM (﻿icewm-1.2.35Latestv2.pet as post by ﻿ttuuxxx here : http://www.murga-linux.com/puppy/viewtopic.php?p=257516. Can I get it back ?

I have an ATI HD4850.... with an adapter on the DVI port that transform it to an HDMI port... going to my 42inch tv...

So basicly, I prefer the sound going to my speaker and not to my tv, but... could by nice at night or when switching from pc to tv to pc etc... In windows I get the sound and video by the HDMI as I wish

In puppies, I never succeed to load the ATI driver completely, I run on a mix of Xorg, catalyst 9.9 and 9.11. The catalyst control center never work, antispec run only one time showing 22fps but now it just give errors... but its ok because I'm able to work in 1920*1080 and surf the web with relative comfort.

I tell that because I think its the main reason why I'm not able to heard sound by my HDMI in puppy. But maybe it will work for you

Ok so now I know that my main speaker are on card 1 device 0 and my HDMI is card 0 device 3

At this point its time to configure new device.
Create a file /root/.asoundrc or edit /etc/asound.conf (its both the same.. one affected to all puppy the other only to your user) I prefer the hidden one in root its easier to find.
Put in it something like:

Just wondering if you found any solution to this yet. I can't find anything on the forums. I just bought a new gateway with intel core i3 intel hd sound and an hdmi jack and it works with windows but not puppy 5.25.
Maybe there is just not enough demand for this type of situation for it to be addressed.
The video comes through great but no sound.

Just wondering if you found any solution to this yet. I can't find anything on the forums.<snip>

I cannot offer you a fix re 525, and hopefully you have found a solution to your problem:
Could I suggest looking at your hardwares web-sites for any flavour of linux drivers and see if your can ascertain which kernel they suggest as a minimum requirement - I tried in vain to install HDMI audio using 528: A switch to a Puppy using a Kernel of 2.6.37.6 and above made the task straight forward.

(529 - ThreeHeadedDog - Luci_001) ? is nicely aged, and would suit the transistion from 525.
